Description

Plastic carrier roller bearing block assembling structure

Technical Field

The utility model relates to a macromolecular material prepares equipment technical field, concretely relates to plastics bearing roller bearing frame assembly structure.

Background

With the progress of polymer material technology, ultra-high molecular weight polyethylene (UHMW-PE) is increasingly widely used. The belt conveyer roller made of the material has the advantages of wear resistance, vibration resistance, noise reduction, long service life and the like. However, during production, the roller made of ultra-high molecular weight polyethylene (UHMW-PE) is difficult to be connected and installed with the bearing seat. Because all plastics are adopted, the adhesive bonding or plastic welding is generally adopted, the strength is unreliable, labor and time are wasted, the production efficiency is low, and the cost is high.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a plastics bearing roller bearing frame assembly structure.

The utility model provides an above-mentioned technical problem's technical scheme as follows: a plastic carrier roller bearing block assembly structure comprises a roller, bearing blocks connected to two ends of the roller in a matching mode, bearings connected in the bearing blocks in a matching mode and a main shaft connected in the bearings in a matching mode and penetrating through the roller; the bearing seat is provided with a convex ring platform at the assembly position of the roller, the inner wall of the assembly position of the roller and the bearing seat is provided with a concave groove matched with the convex ring platform, and the convex ring platform is embedded in the concave groove.

Furthermore, the convex ring platform and the bearing seat are of an integrated structure.

Further, the bearing seat is in interference fit with the roller.

Furthermore, the bearing seat and the roller are both made of ultra-high molecular weight polyethylene materials.

Further, the height of the convex annular platform is matched with the depth of the concave groove.

Further, the number of the convex annular platforms is consistent with that of the concave grooves.

The utility model discloses following beneficial effect has: the utility model provides a plastics bearing roller bearing frame assembly structure, its structure is reliable, and the installation is quick, and the hookup is reliable, and the processing of the concave groove of this roller and bearing frame installation department and protruding type ring platform can not produce extra cost, during the installation, directly impresses the roller end with the bearing frame, compares traditional glue and bonds or the plastic welding, easy operation practices thrift manual work and material, and efficiency improves. The matching of the groove and the convex annular table ensures that the roller and the bearing seat are tightly combined in the radial direction to form axial fixation and prevent axial separation; through the interference fit of bearing frame and roller, form the radial fixed of bearing frame and roller, improve holistic stability, guarantee production quality.

the reference numerals shown in fig. 1 to 3 are respectively expressed as: 1-roller, 2-bearing seat, 3-bearing, 4-main shaft, 5-convex annular table and 6-concave groove.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1 to 3, a plastic carrier roller bearing block assembly structure comprises a roller 1, bearing blocks 2 connected to two ends of the roller 1 in a matching manner, bearings 3 connected in the bearing blocks 2 in a matching manner, and a main shaft 4 connected in the bearings 3 in a matching manner and penetrating through the roller 1; the bearing seat 2 is provided with a convex ring platform 5 at the assembling position of the roller 1, the inner wall of the assembling position of the roller 1 and the bearing seat 2 is provided with a concave groove 6 matched with the convex ring platform 5, and the convex ring platform 5 is embedded in the concave groove 6. The number of the convex ring platforms 5 is the same as the number of the concave grooves 6.

Bearing frame 2 and roller 1 are the ultra high molecular weight polyethylene material and make for both all can produce plastic deformation, during the installation, directly impress bearing frame 2 roller 1 end, compare traditional glue bonding or mould and weld, easy operation practices thrift manual work and material, and efficiency improves. And through the cooperation of recess and protruding type ring platform 5, guaranteed that roller 1 and bearing frame 2 are radial closely combined, form the axial and firmly prevent the axial and break away from, improve the inseparable stability of assembly between bearing frame 2 and the roller 1.

Protruding type ring platform 5 is the integral type structure with bearing frame 2, and this protruding type ring platform 5 directly forms on this bearing frame 2 processing, can not produce extra processing cost, saves manual work and material.

The bearing seat 2 is in interference fit with the roller 1. Through interference fit between the bearing seat and the roller 1, radial fixation of the bearing seat 2 and the roller 1 is formed, and connection assembly strength is improved.
